The XAccessibleTable interface is used to represent two-dimensional tables. This interface combines the two interfaces javax.accessibility.AccessibleTable and javax.accessibility.AccessibleExtendedTable of the Java Accessibility API (version 1.4).

All XAccessible objects that represent cells or cell-clusters of a table have to be at the same time children of the table. This is necessary to be able to convert row and column indices into child indices and vice versa with the methods XAccessibleTable::getAccessibleIndex(), XAccessibleTable::getAccessibleRow(), and XAccessibleTable::getAccessibleColumn().

The range of valid coordinates for this interface are implementation dependent. However, that range includes at least the intervals from the from the first row or column with the index 0 up to the last (but not including) used row or column as returned by XAccessibleTable::getAccessibleRowCount() and XAccessibleTable::getAccessibleColumnCount(). In case of the Calc the current range of valid indices for retrieving data include the maximal table size--256 columns and 32000 rows--minus one.
